Description and Introduction

Q1 The TPS60402QDBVRQ1 is a charge pump voltage inverter manufactured by Texas Instruments (TI). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:  

### **Manufacturer:** Texas Instruments (TI)  
### **Part Number:** TPS60402QDBVRQ1  

### **Description:**  
The TPS60402QDBVRQ1 is a charge pump DC-DC converter that inverts a positive input voltage to a negative output voltage. It is designed for applications requiring a low-noise, regulated negative supply.  

### **Key Features:**  
- **Input Voltage Range:** 1.6V to 5.5V  
- **Output Voltage:** -1.6V to -5.5V (inverts input voltage)  
- **Output Current:** Up to 60mA  
- **Fixed Switching Frequency:** 250kHz  
- **Low Output Ripple:** Low-noise charge pump operation  
- **Low Quiescent Current:** 65µA (typical)  
- **Shutdown Current:** <1µA  
- **Regulated Output:** Maintains stable inverted voltage  
- **Package:** SOT-23-5 (DBV)  
- **Automotive Qualified:** AEC-Q100 compliant  

### **Applications:**  
- Generating negative supply rails in portable devices  
- LCD bias supplies  
- Operational amplifier (op-amp) power supplies  
- Automotive systems  

This information is based solely on the manufacturer's datasheet and specifications.

Application Scenarios & Design Considerations

Q1

Alternative Part Number

  • LM2664M6X/NOPB --: Pin-compatible switched-capacitor voltage inverter in SOT-23-6 with similar 60 kHz operation and 1.8-5.5 V input range, suitable drop-in for many TPS60402QDBVRQ1 designs.
  • MAX1044ESA+ --: Classic charge-pump voltage inverter with comparable inversion function and current capability, widely available and often used as a second source for inverting regulators.
  • ICL7660ACBAZA --: Industry-standard monolithic charge-pump voltage converter providing negative output from positive input, a common alternative when the TI automotive-grade part is unavailable.
